Polispec NIR is the instrument of excellence of the range, it is a robust and compact spectrophotometer, made both for portable use and for in-process installation. It is available in the near infra-red spectral ranges, between 900 and 1700 nm. It has been designed considering various technological approaches that make it highly performing in terms of sensitivity, operational dynamics and signal cleanliness.
These qualities make Polispec NIR suitable for analysing very different matrices, from the most reflective to the most absorbent, without the need for different versions of the instrument for each application area. The casing is made entirely of anodised aluminium, while a large
heat sink is located at the front to remove the heat generated by the lighting system and the active cooling system of the sensor. Adaptable to different types of applications (reflection, transmission, contactless…), in its standard configuration in reflectance Polispec
NIR integrates a diffuse/0° optics and a system of automatic internal references which, as well as for the acquisition of the measurement, can be controlled by two buttons. The area framed by the collection optics is extremely large and particularly suitable for the analysis of whole products and for product flows in motion.
For in-process installation, the tool/machine coupling can be created in different shapes and materials in order to be adapted to the most particular needs (for example in the food and industrial sectors).
The software interface is extremely simple, intuitive and compatible with different calibration suites for users who wish to develop their own chemometric models. We have created the entire software infrastructure to be easy to use both independently and for easy integration, for example, with plant PLC systems or machine CAN protocols. The instrument itself can be configured for different communication protocols in order to make its use even easier.
